See the "Versions" note on that page. In another post, you say you are 
installing RT 3.6.6, but below it looks like you are trying to install 
RT::Authen::ExternalAuth 0.08. That won't work. I'm not sure that it is the 
source of your current issue, but you should get compatible versions before 
proceeding.

Obviously the second one is not the right RT.pm It, but the others are also 
in very odd places for RT.pm. Typically RT's perl modules are NOT installed 
under the general-use perl directory tree, but in a distinct directory such 
as /opt/rt3/. The specific layout is defined as part of the build/install 
process, and results in the various paths being defined in the RT.pm that 
gets installed. If you start moving parts of RT around after installation, 
you will break it.

> Path to your RT.pm:

3 possibilities:

1. This is because of the version mismatch.
2. That RT.pm is not the RT.pm you are looking for, i.e. it is not the 
top-level module for Request Tracker.
3. That RT.pm is not readable by the install process. (one might achieve 
such an oddity with something like SELinux)
